I'm no expert, but I think this is incorrect. The resistance of the bulb remains the same when it's hooked up to 12V battery, therefore the current it draws should be 0.083 amps (i.e. 1/10th of what it draws at 120V).
This turns the bulb into a 1watt (12V * 0.083amps) bulb; i.e. its glow...
You're right; 300F is too cold.
That's an interesting idea with the embedded lighter, but it seems to be way out of my know-how to execute.
The tobacco getting stuck on the element is a pain, but interestingly some smokers (according to my friend) still prefer the element to the flame...
always. Otherwise, a standard car cig-lighter would serve the purpose. The device is for a friend's cigar-lounge; many of his customers prefer to light up using the car cig-lighter; probably the most practical option is to have a bank of these available in the lounge, but he and I were...
Thanks for the reply berkeman. Please, just humor me... it may be a hair-brained idea but has aroused my interest/curiosity enough that i would like to see it through. Thanks for any help.
Hi,
I am not an electrical-engineer, but a hobbyist/tinkerer... I want to create an electric cigar-lighter that can be "always-on" and was hoping that someone here could answer some questions.
The lighter needs to work in a car cigarette-lighter socket; i.e. 12V DC with 10-15 amps max...
